The built-in lithium ion battery lasts about 3-4 hours. The battery is charged through the USB micro port. The WiFi range is over 400 ft / 120m, though the range depends greatly on the exact location and scenario. The CamRanger Mini works with most Nikon and Canon DSLRs. The included case can be used for storage and to attach to the camera or tripod.
The CamRanger Mini app is available for iOS and Android as a free download from the Apple App Store and Google Play Store.
Both the Android and iOS apps have been completely revamped from the original CamRanger app.
